[PATCH] nsproxy cloning error path fix
This patch fixes copy_namespaces()'s error path. when new nsproxy (new_ns) is created pointers to namespaces (ipc, uts) are copied from the old nsproxy. Later in copy_utsname, copy_ipcs, etc. according namespaces are get-ed. On error path needed namespaces are put-ed, so there's no need to put new nsproxy itelf as it woud cause putting namespaces for the second time. Found when incorporating namespaces into OpenVZ kernel.
